However, when considered together, those findings lead to three main conclusions: As a field, computer science education professional development needs to move toward more coherence. As a field, computer science education professional development needs to move toward better fitting the needs of the groups that will comprise the computer science teacher workforce. As a field, computer science education professional development needs to focus more on teaching and learning in the classroom.

Tufte in His Own Words. Primary Website. Primary Website. Primary Website. Stephanie Evergreen. About John Snow. John Snow is an iconic figure in epidemiology and public health, best known for his work on cholera, for a famous map, and for organising the removal of a pump handle in Soho.

Less well known are his important contributions to anaesthesia and to epidemiological methods, and his engagement in public debates of the time. The breadth and depth of Snow’s activities provide a model for population researchers concerned not only with sound method but also with bringing their results to public benefit.

Indeed, though epidemiology is often described as the study of health-related aspects of populations, its methods are applicable to studies of virtually anything in populations, and disciplines which now acknowledge the methods and terminology of epidemiology range from education to crime science and economics.
Susnpot Drawings. Galileo's Sunspot Drawings In 1612 during the summer months, Galileo made a series of sunspot observations which were published in Istoria e Dimostrazioni Intorno Alle Macchie Solari e Loro Accidenti Rome (History and Demonstrations Concerning Sunspots and their Properties, published 1613).

Because these observations were made at appoximately the same time of day, the motion of the spots across the Sun can easily be seen. To illustrate this, thirty-six of Galileo's sunspot drawings have been placed in sequence as "flip-book" type animation which can be played at two different speeds. The faster animination better demonstates to movement of the sunspots. The slower animation affords the opportunity for more careful study of Galileo's drawings. Animations Several file formats are available for making computer animations--each with its own advantages and disadvantages. MPEG Animations: Smaller file size, but lower quality images.

XKCD Comic. Galileo Project. Sunspots Sunspots are dark areas of irregular shape on the surface of the Sun.

Their short-term and long-term cyclical nature has been established in the past century. Spots are often big enough to be seen with the naked eye. While direct observation of the Sun in a clear sky is painful and dangerous, it is feasible when the Sun is close to the horizon or when it is covered by a thin veil of clouds or mist. Records of naked-eye sunspot observations in China go back to at least 28 BCE. The scientific study of sunspots in the West began after the telescope had been brought into astronomy in 1609.
